MD driver is "multiple devices." This is used for functions such as making two partitions perform as one large partition ("RAID 0," etc.). Most people do not use the MD driver, but it is needed at install time. The reports I've read suggest hardware is being detected by the MD driver and an attempt is made to initialize the hardware, however either due to a system bios bug (I read reports that some system bios' were to blame) or an MD driver bug, I'm not sure which, hardware is improperly detected by the MD driver and the system hangs. Certainly you should remove any hardware that is not needed for installation. If you have a device that you suspect may cause a problem and you need it for install such as a scsi adapter for your hard drive and you can find the hardware address for it, you may be able to exclude this address at the LILO boot prompt using an exclude statement and initialize that device manually, but most reports I've seen have no such hardware. I have seen a report that the MD driver included with newer kernels may provide a solution (workaround or bugfix, I don't know). The report said that kernels 2.0.33 and 2.0.34 (in hamm) do not work, and kernel 2.0.36 (in a redhat boot disk) does work. The good news is that the MD driver was updated at kernel 2.0.35, and I'm told the slink boot disks have kernel 2.0.35, so slink boot disks (in frozen) may provide a solution. Since slink is due to release shortly, this would save you from upgrading and provide the latest software. You may want to try some other boot disks: http://www.debian.org/~adric/aic7xxx/ However, I think these are intended for improperly detected scsi adapters which hang the system during the scsi initialization phase, not the MD driver initialization phase, so they may not help.
